Welcome to the forums, and to Scrivener. Fellow customer here.
DropBox syncing is super easy, but if you don’t want to use it, that’s your choice.
The problem for you is that DropBox is currently the only L&L supported option for syncing Scrivener on iOS. My understanding, from reading many posts by the developer on the topic, is this is unlikely to change anytime soon. Here is the Knowledge Base page that discusses iOS syncing, see at the very end a brief note as to why no other syncing options:
The only other official method I am aware of for sharing (not syncing) projects from iOS is to use iTunes to manually copy your projects between iOS and your PCs. That involves a cable. I have never done it, so am not clear on the steps involved, but you can search the forums for this if you’re interested. ETA: Looks like the steps for copying via iTunes are in the iOS tutorial, accessible from the bottom of iOS Scrivener’s projects screen. See the “Working with Projects” doc.
I think you possibly could share projects via zipped backup files. So you’d do some work on your PC, create a zipped backup, save it somewhere to the cloud, then access it from your iOS device and extract & copy into Scrivener. You should also be able to go the other direction. Sounds labor intensive to me, but it should work. This is decidedly unofficial, I’ve never done it, and you’d need to reverse engineer how to accomplish it from this post:
ETA: Just to be totally clear, I brainstormed this method as I was typing this post. I don’t know of anyone who has actually done it. It might not work. If you decide to try it, use a test project first! 8)
For your last question, if you want to move a project out of DropBox:
- Start iOS Scrivener
- From the Scrivener Projects list, click Edit
- Drag the project you want to move down from the DROPBOX section to the ON MY IDEVICE section.
The project will be moved out of DropBox, and you will only be able to access it from that iDevice.
